Sarangerel (Сарангэрэл) is the Mongolian word for "moonlight" — combining saran (moon) and gerel (light).
Used widely in Mongolia.
Sarangerel does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Sarangerel reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
